SCAVENGEB Specification of Letters Patent.

Application flied November-'20, 1907. Serial No..403,0fl.

To all whom it may concern:

Be it known that I, STEPHEN B. SHirP, a citizen of the United States, residing at New Brookland, in the county of Lexingtonand State of South Carolina, have invented certain'new and useful Improvements in- Scavengcr Mechanisms, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention rovides means whereby waste, broken ends, or sliver, formed on thread and the like in s inning, twisting,

I given to the scavenger-rollers when this occurs, the material on the scavenger-rollers continues to enlarge until so much material accumulates on them that it attracts other threads or ends and causes them to break down, thus multiplying the first trouble. Uneven product and what is called gouts often result, which will cause the material to break down in some subsequent process in which it is used and eventually make a defective output.

The scavenger-rollers have to be cleaned from time to time by the operative by removing the rollers from the frames and stripping the accumulations off by hand. This often breaks down more ends, making more imperfect work and consuming a large amount of time.

This invention is designed to avoid these difficulties and the necessity of'frequent at tention to these parts of the machine by the operative. For this purpose a scavengerconduit of novel construction is located adj a cent to the drawing-rollers in much the same position as usually occupied by the scavenger-roller commonly employed, the location of this conduit being such as to in no way interfere with the folding back of the threadguides in the dofling operation; Means are provided whereby an induced current of air or suction is produced in this conduit, whereby waste, slivers, and the like are drawn off the material into the conduit through openings therein after passing through the drawing-rollers and thence through other conduits' to any suitable place ofaccumulation. The waste is thus kept off the floor and prevented from choking the drawing-rollers and other parts of the machinery, and the expense of renewing roll-covering is very materially reduced. Further, the expense of the manual removal of the waste from the room is avoided.

The scavenger-conduit is positioned in the same seats as were formerly occupied by the scavenger-rollers, thus avoiding the necessity of in any way changing existing mar chines to accommodate it.

When read in connection with the further description hereinafter, the details of construction and arrangement of parts contemplated by this invention will be apparent from the accompanying drawings, forming part hereof, wherein a preferable embodiment of the invention, as applied to a spinning-machine, is disclosed, for purposes of illustration.

Like reference-characters refer to corresponding parts in the several views of the drawings, of which Figure 1 is a fragmentary side'view of a spinning-machinehaving my invention applied thereto; Fig. 2- is a transverse sectional View thereof; Fig. 3 is a view of the scavenger-conduit; Fig. 4 is a transverse-sectional view thereof; and Fig. 5 is a view of'a supporting-arm for a scavenger-conduit.

Having more particular reference to the drawings, 6 designates the roller-beam, 7 the rollerstands, 8' the drawing-rollers, and 9 wei hted arms, pivoted to the roller-stands, of the characterusually employed to-maintain the scavenger-rollers in contact with one of the lower sets of drawing-rollers, the arms having seats 10=thereo1r Inplace of the scavenger-rollers, this invention provides for each set of drawing-rollers a scavenger or exhaust conduit 11. This ,conduit has orifices 12 therein, one of which is positioned under each lower outside drawing-roller. The exterior top side of the conduit is formed with a depression around each orifice, as shown at 13, in order to afford better facilities for waste to be drawn through the orifices. This depression is rounded in cross-section to conform, more or less, to the periphery of the drawing-roller.

On each end of the scavenger-conduit is a pin or projection 14, which is arranged to rest m a seat 10 in a pivoted arm 9, the conduit being thereb supported in place. In order to prevent t e conduit from bein brought into contact with the drawing-r0 ers, as is the case with the scavenger-rollers, a flange projects from each end of the scavengerconduit and is positioned above pin 14, this flange'being arranged to engage the bottom 'of the roller-stand. The flange is preferably so located as to permit the conduit to assume a position about one-eighth'inch from the drawing-rollers. The scavenger-conduit increases in size of cross-section from one end toward the other, to accommodate the increasing amount of air and waste drawn toward one end.

To' the larger portion of each scavengerof the conduit, so that it may be lifted off in much the same manner as were the scavenger-rollers.

Each branch-pipe 18 of a machine leads to a main conduit 19 extending longitudinal] of the machine, preferably under the cree boards. At the end of conduit 19 is a fancasin' 20, containing a fan 21, driven by a belt 52 from the driving-drum 23. This fan induces a current of air toward it in the before-mentioned conduit and pipes and draws the waste from the thread therethrough, forc' it through a pipe 24 to a condenser 25, i%1ence it is drawn through a pipe 26 to a trunk-conduit 27. Conduit 27 is located beneath a series of machines, preferably (under the floor, and leads to the pickenroom or any other suitable place in the mill, where a fan is located to produce suction in the conduit and where waste is so arated from the air.

t will be noted that the placing of the scavenger conduit directly ben'eathi and close to the drawing-rollers obviates an inl ding .terference by the conduit with the f0 back of thethread-guides and thread-boards said element, and a fla in the dofiing operation which interference would occur if the conduit were located in proximity to the thread'at any other point etween the drawing-rollers and the eyes of the thread-guides.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is y 1. In a scavenger mechanism for textile machinery, and in combination with a series of dra -rollers, a scavenger-conduit positioned adjacent to said rollers, said conduit having an orifice therein for each roller and being formed with depressions surrounding the orifices conforming to a certain degree to the periphery of the rollers, and-means whereby suction is produced in said conduit.

2. In a scavenger mechanism for textile machinery, the combination with an element over which material passes, of a scavenger-conduit, means for movably supporting said conduit adjacent to said element,

and means for limiting the proximity of said D element and conduit.

3. In a scavenger mechanism for textile machinery, the combination with a support and an element thereon over which material passes, of a scavenger-conduit, means for movably supporting said conduit adjacent to e on said conduit and engageable with sai support whereby the proximity of-said element and conduit is limited.

4. In a textile machine, a scavenger mechanism comprising a scavenger-conduit lo-- cated adjacent to each series of elements over which material passes, a branch-pipe connected with each scavenger-conduit, a main conduit extending longitudinall of the machine and connected with said ranchpipes, means on said machine and connected with said main conduit whereby suction is produced therein, a condenser with which said suction means communicates, a trunk conduit, and a conduit connecting said condenser and trunk-conduit.

In testimon whereof I aflix my signature in presence 0 two witnesses.
